Key result
Stentless bioprostheses displayed superior haemodynamics compared to stented or mechanical prostheses at 1 year postoperatively, though without differences in left ventricular mass reduction.
Why the study?
Do stentless bioprostheses improve haemodynamic performance compared to stented or mechanical prostheses in patients undergoing aortic valve replacement?
Cohort (n=106)
Do stentless bioprostheses improve haemodynamic performance compared to stented or mechanical prostheses in patients undergoing aortic valve replacement?
Stentless bioprostheses offer superior haemodynamic performance resembling normal native valves compared to stented or mechanical prostheses, though without a difference in left ventricular mass regression at 1 year.
No takes yet. Share an insight, caveat, or question.
Stentless valves' haemodynamic edge should not alter AVR practice; leaves open randomized confirmation of clinical benefit beyond 1 year.
Khoo et al. (2012) conducted a cohort in Aortic valve replacement (n=106). Stentless bioprostheses vs. Stented or mechanical prostheses was evaluated on Haemodynamic performance (gradients, effective orifice area, dimensionless severity index, resistance). Stentless bioprostheses displayed superior haemodynamics compared to stented or mechanical prostheses at 1 year postoperatively, though without differences in left ventricular mass reduction.
